USB HID Device Troubles

General Discussion

Using a BeagleBone Black Revision C. I am having some trouble with a HID Device (iMX8 Processor)
I get the following when attaching the device,

This can go on for a while, once it does finally connect it seems to be ok, i can unplug and plug it back in and it finds it straight away.

I don’t think it is an issue with the device/cable as i don’t have any issues connecting on other linux or windows systems.

I am using the most recent default buildroot configuration for beaglebone (kernel 6.1.46-ti-r13).
I have also tried with the released “am335x-eMMC-flasher-debian-12.2-minimal-armhf-2023-10-07-2gb”. I get the same issue however it seems to be more reliable and will connect after a few retries.

I’m not sure how to tackle this problem, from what i have read the “error -110” is a timeout error. Some people have suggested power rail issues. I tried putting some extra capacitance on the USB Power line but this did not make a difference.

some more info about the device,
from lsusb -v (on Ubuntu system)

Might be a power problem. How are you powering the BBB and how much current does the iMX8 device need ?

If you have a powered hub, try using that see if it helps.

I am powering the BBB via the 5V DC jack with a 2A supply.

If you have a powered hub, try using that see if it helps.

Great Idea. I don’t have a powered hub on me. but i tried with a regular hub and I no longer get the issue. I don’t know enough about USB protocols to make sense of why this worked.

I Revisited this recently as I was still having some issues with USB Hubs.

I fount that adding the usb port quirk “USB_PORT_QUIRK_FAST_ENUM” mostly resolved the problem.
I still get the occasional disconnect, however it reconnects straight away and no longer gets stuck in the loop initially described.

The quirk can be enabled in user space by,

echo 0x2 > /sys/bus/usb/devices/1-0:1.0/usb1-port1/quirks
